I don’t understand the confusion here as they’re both bools that when checked = true. As DomusLudus explained; Visible is like saying "Is this object Visible? and Hidden in game is like saying "Is this object hidden in the game (IE when playing). You can have something be both Visible and Hidden in game as one is for use in Editor and the other is while the game is running. “Visible” toggles the actor’s visibility regardless of the state (editor or gameplay). “Hidden in game” is used when you want the actor to be visible in the editor but not in the game while you play. There are a million use cases where you want something to be invisible to the player, but you still want to be able to see it while in the editor for placement etc.
